Abstract
a. Tube cathodique à fibres optiques ayant une plaque avant formée par un empilage de fibres optiques formé d'un grand nombre de fibres de verre, parallèles, de petit diamètre, les extrémités des fibres formant la surface interne et la surface externe de la plaque, une couche de phosphore étant déposée sur la surface interne de la plaque. b. Tube cathodique caractérisé en ce qu'il comporte une couche mince, transparente à la lumière, entre la couche de phosphore et la surface interne de la pile de fibres optiques formant la plaque. c. L'invention s'applique notamment aux photocopieurs.
